All the major players in the Pinnacle Bank Arena construction projects have clocks on their desks counting down to September 2013.
Friday, those clocks read 380 days until the $150 million building needs to be completed in time for Husker basketball.
Media toured the construction site Friday as workers put roof trusses up overhead and installed some pre-cast concrete for seats.
More than 200 workers and 10 subcontractors are on site doing concrete, steel and electrical work.
Other notable milestones -- the main concourses are laid, all the concrete pillars that go into the ground are done and the lobby area almost is enclosed.
"It's a big week for the arena," said John Hinshaw, construction manager with Mortenson/Hampton Construction, pointing to the steel structure of the trusses.
The total combined weight of the trusses is 400,000 pounds.
A big week indeed, as the building comes to near-half completion. Construction began in November 2010.
One crane will poke through a hole in the roof of the arena until mid-January.
The steel work for the roof should be completed by November. That's when the construction company and the city will host a "topping out" ceremony, a construction tradition held when the last steel beam is placed.
The milestone is part of a construction video created by Mortenson Construction, which shows the timeline of what work needs to happen when.
The video, with bright colors that represent different types of work and phasing, gives construction workers and other officials an idea of what the arena will look like on any given day.
"It's more of a video for us to visualize what's supposed to happen," Hinshaw said. "It's different than an architectural rendering that shows what it actually looks like."
The 3-D video is only one of the technological tools in their belt.
The project is nearly paperless as all drawings and blueprints are on computers, iPads or other devices on site.
So far, there has been 271,045 worker hours on site.
More than 60 percent of the 1,448 workers that have been on site are from Lincoln and another 27 percent are from Nebraska, outside of Lincoln.
Local participation in design and construction has been a major focus of the project, said Hampton Construction President and CEO Bob Caldwell.
"We really have to credit the joint public agency for putting attention on using local talent," he said.
More than $136 million from the project has been put into the Nebraska economy, according to arena officials.
